An anal fissure is a break or tear in the skin of the anal canal. Symptoms associated with acute fissures include pain with defecation, anal spasm, and bleeding with defecation. Fissures persisting for longer than four weeks, or recurrent fissures, are defined as chronic. Half of patients with fissures heal with nonoperative management, and surgical treatment, if required, has a high success rate.
